Rule department scholar

Now is also an opportunity to prove that the website is safe, and it is impossible for computer experts to break through it.

this evening.

Li Jiandong routinely checked the website before going to bed, and immediately felt relieved. The picture on the main page of the leader's inspection was tampered with, and a flash animation of an eagle flying was shown.

"Yiying?"

Li Jiandong clicked on the picture and found the link.

A weird song sung a cappella was played, and the more Li Jiandong listened to it, the more irritable he became. If the webpage was tampered with, it meant that it had been compromised. Isn't that a direct mockery of his work?

Li Jiandong hurriedly logged in to the management page, wanting to modify the webpage back, but after clicking in, he found that it could not be modified at all.

Need permissions?

Want to enter a password?

Li Jiandong was depressed to find that he couldn't modify it for the time being. He had to find the source code on the computer in the bureau before he could directly delete and modify it.

According to the normal process, after someone breaks through the website, they will ask the other party to submit a security vulnerability. After the vulnerability is patched, the security will naturally improve.

Li Jiandong didn't want to do that.

If the other party reports the security breach, the higher-ups will definitely know about it, which is equivalent to drawing an 'X' on his work, and he and the logistics department will lose face.

Li Jiandong thought about it and decided not to submit it. He went to the bureau early tomorrow to modify the source code on the computer.

He also knew what the problem was--

The other party must have entered the management page in order to make so many modifications. It is like designing a web page, with links embedded in the animation.

So... change your password!

As long as you change a complicated management password, it will be impossible for the other party to crack it easily.

Chapter 99 Guessing the answer is meaningless

On the big news picture of the Zhengyang police website, a flash animation of an eagle flying is displayed, and when you click on it, there is a DJ singing a cappella.

This matter was known by many people.

People outside know less. The police website has not been established for a long time. It is only used to publish some information and does not provide any convenient services. Few people will click on it.

People who work in the police department, from the leaders of the department to the cleaners who clean the stairs, all know it.

Lots of people talking in the morning, most just laughing at it.

It's not a secret that the website is undergoing a security upgrade, but the logistics department didn't announce it on the website. They are more interested in the a cappella dj.

Although it sounds weird without a soundtrack, the tone and lyrics are very interesting.

Many people also know the name of 'Yiying'.

"Who is this Yiying? Captain Lin recommended it. It's really powerful. It hacked the website in one day."

"The group of people in the logistics department don't know anything about websites or security at all. If you want me to say, these new things, technological things, need to be managed by special people, like this Yiying. It has greatly improved network security, at least I am not afraid that the Penguin will be stolen."

"Hahaha, don't you know? Captain Lin's Penguin may have been stolen yesterday, and he logged in from the computer in the office."

"Now that hackers have infiltrated our department, the group of people who count on the logistics have no security at all."

The logistics people must not be happy to hear that.

Li Jiandong came earlier than the others. He entered the office at six o'clock, turned on the computer to find the source code, and called the database to overwrite the modified pictures and links. Because of the speed of the network and the influence of wrong operations, the website was paralyzed for more than ten minutes.

Of course, it doesn't matter.

After six o'clock, no one will be idle to check the website.

What Li Jiandong didn't realize was that all his operations were transmitted to the server through a device called a 'router', and the router used by the police department has been remotely monitored 24 hours a day.

morning.

Zhou Hongwen, the leader of the logistics department, found Li Jiandong and talked about the hacking of the website yesterday.

Li Jiandong's answer was like this, "I know how the other party breached the website, just fix the loopholes directly, there is no need to report to the above, let the other party submit the loopholes?"

It makes sense for Zhou Hongwen to think about it.

The police department's website is managed by the logistics department. Knowing that the loopholes can be patched directly, there is no need for the other party to submit them. The record of "vulnerability reported by outsiders" is also a small stain on the work of the logistics department.

More importantly...

'Yi Ying' is a person recommended by the criminal investigation department, not by the logistics department. The above means that all departments can recommend people, but a group of investigators from the criminal investigation department, the person recommended broke the website, and the logistics department The recommended person didn't even do anything?

This is a slap in the face!

Zhou Hongwen decided to trust Li Jiandong and did not report according to the established procedures.

Lin Xudong and the criminal investigation department were unhappy, but there was nothing they could do about it being suppressed by the logistics department.

noon.

Lin Xudong called Zhao Yi and talked about what happened in the morning with apology, "You succeeded yesterday, but you were suppressed by the logistics. The things inside are a bit complicated, so I won't go into details with you."

"Anyway, I'm really sorry. How about it, I personally reward you with 1000 yuan."

Zhao Yi was a little surprised.

He thought it was over.

He made a routing monitoring software, hacked the website of the police department, submitted a question according to the procedure, reminded the police to hide the management website entrance, upgraded the security and encryption of the routing, and his work was completed.

He didn't care about how much money he could get for this job.

A few thousand dollars is nothing, just an hour of leisure part-time job, even if there is no penny, it can be regarded as helping the police department and improving network security.

Sounds... kinda great!

Zhao Yi didn't plan to continue doing anything. After all, he is not an insider of the police, so there is no need to spend too much time and energy on the security of the police website.

That's not greatness, that's sickness.

Hearing Lin Xudong's explanation, Zhao Yi was secretly upset. Even if he didn't care about the bonus, he couldn't be suppressed like this, right?

"No, Uncle Lin." Zhao Yi asked after refusing, "Then do you still need my help? How about I go back today and go to your website to hang a picture?"

"You can still go in?" Lin Xudong was a little surprised.

Zhao Yi asked, "Why not? Do you know how I got in?"

"I am not sure."

Lin Xudong didn't understand network technical problems, but he knew that the logistics had suppressed things, which meant that he had found a loophole. He also felt very depressed. Hearing Zhao Yi said that he could still go in, he suddenly said with some expectation, "If you don't delay Time, you can try again, make it bigger, it doesn't matter, don't worry, I have you, Uncle Lin!"

"I've already reported your name, and the police know that 'Yi Ying' is one of our own."

"The bonus will be paid at that time, and I will personally subsidize you..." Lin Xudong gritted his teeth and said a number, "Two thousand!"

"Thank you in advance."

Zhao Yi smiled and put down the phone.

Lin Xiaoqing was lying on the table, staring at him with blinking eyes, "What did my dad ask you to do?"

Zhao Yi glanced left and right, put his head next to his little ears, and whispered slowly, "Secret!"

Lin Xiaoqing pricked up her ears, and almost exploded when she heard the word 'secret'. She sat up and pouted, "You don't even say anything, what are you doing here mysteriously?"

Zhao Yi said with a smile, "You have a fragrance on your body, I will smell it!"

"What are you talking about? Shameless!"

Lin Xiaoqing blushed when she heard this, and quickly turned her head away. She turned around after a while, and still couldn't hold back her curiosity with a soft 'hum', "What exactly are you doing, tell me."

Zhao Yizheng was immersed in the joy of 'learning coins + 3', and after hearing Lin Xiaoqing's question, he felt that he should continue to work harder.

In one breath!

Accumulated learning coins!

He leaned over again, pointed at his cheek and laughed, "Well, you... hehe, I'll just say it!"

Lin Xiaoqing took a deep breath, stood up abruptly and slapped the table.

"Oh!"

The whole class looked over.

She just stared straight at Zhao Yi, and kept rubbing her wrists, as if she was going to beat someone up, "Say it or not!"

Zhao Yi knew that Lin Xiaoqing was just trying to scare people, and every time he put on a violent posture, he actually didn't do anything at all, but he still pretended to be scared, and kept waving his hands and said, "Heroine, spare me! Don't, don't, don't , haha, I say! I say!"

Only then did Lin Xiaoqing sit down satisfied.

Zhao Yi said, "Actually, it's not a secret. Some time ago, Zheng Yang's police website was attacked by hackers..." He said briefly.

Zhao Linlin also poked her head over to gossip.

This kind of thing is really interesting for the little girls in high school. When they heard Zhao Yi say 'continue to invade', they chattered about how to modify it, which was even more interesting.

"You just put a picture of an eagle? How boring!"

"Should change to a spoof picture!"

"Change the background to the Thirteenth Middle School, and then the police website will become an education website..."

Zhao Yi ignored it.

This is really what a little girl said casually.

That is the police website of Zhengyang City, no matter how bad it is, it is the website of the state department, even if it is a spoof, there must be a limit, leaving traces to indicate a successful intrusion is enough.

After each suggestion was directly rejected by Zhao Yi, they diverged their thinking in other aspects.

Zhao Linlin is worthy of being a little witch.

Each of the suggestions she put forward made Zhao Yi's eyes brighten, and he decided to adopt one of them.

……

It's past nine o'clock in the evening.

When Zhao Yi got home on time, he rushed to the computer, opened the management page of the police website, logged in and found that he couldn't get in.

"Changed the password?"

He turned on the monitoring software.

The monitoring software is always on, and a lot of content has been added in one day, because he knows that the website was restored in the morning, and he found the content he wanted without careful screening--

A login ID, several new passwords.

"Has it been changed several times?"

Zhao Yi tried the passwords one by one, and soon logged in again. He continued yesterday's operation, replacing the big news picture with the animation of the eagle, and then put a link directly to the recorded DJ Divine Comedy.

What happens next is different.

He raised the permission to modify pictures and links to the highest level, which can only be modified from the source code library.

If the other party does not know the password, there are two options for modification: either brute force cracking, which is technically difficult; or directly modify the underlying code, and re-upload and load the website.

The second operation is different from the previous day.

The day before, you only need to use the source code to directly overwrite the content of the database, and you can remove the Flash animation and links of the eagle, but if you upgrade to the highest level of modification, the database cannot be overwritten, so you must temporarily close the external access. After the modified source code is uploaded to the server, restart the server.

Due to the delay of the network operator's service, the website will be paralyzed for at least a few hours.

Of course.

It is impossible for Zhao Yi to paralyze the police website for several hours, and he still left a back door for recovery.

If someone enters the management page, they will be able to see a hidden high school function question next to the eagle animation.

This function problem is very brain-intensive, and ordinary students can't do it at all. Even with Sun Liang's mathematical ability, it takes a long time to think hard to solve it.

There is a sentence below the math problem--

[The answer to the question multiplied by pi is the final digital code. (Special reminder: if the password has more than ten digits, guessing the answer is meaningless/smile)]

After Zhao Yi finished the operation, he took a screenshot and sent it to Lin Xiaoqing, asking Lin Xiaoqing to help forward it to Lin Xudong, asking if it was too much.

Lin Xudong burst into laughter when he saw the screenshot.

math problem?

Good idea!
